Abstract (en)
[origin: EP1437726A1] A light-curable transfer sheet has a light curable layer comprising a light-curable composition which contains a reactive polymer having photopolymerizable functional groups and which can be modified by pressure. Independent claims are also included for: (1) a laminate where a light curable layer of the sheet is adhered on the rough surface of a stamper having roughness on the surface as recording pits and/or grooves; (2) a lamination method where a laminate is formed by pressing the light curable layer of the sheet on the rough surface of the stamper; (3) an optical information recording substrate which has recording pits and/or grooves; (4) the manufacture of the optical information recording substrate; (5) an optical information recording medium; and (6) the manufacture of the optical information recording medium.
